Combining multiple clips into one in FCE4

Hey all, I have several clips that I would like to combine into one in Express, preferably without exporting them, so that I can resize them (I'm going to have two clips side by side) in the canvas all at once. If there's a way to do this I'd love to know how!
I've attached a photo as reference- I'd like to unite all the clips in each line into one.
